Question

1) utility class, use only static methods, block copying and creation

class myUtils
{
public:
    static void utilFunc();
    static void utilGreatFunc();

private:
    utils() { } // block creation
    utils(const utils &) { }
    ~utils() { }
}

2) use namespace

namespace myUtils 
{
    void utilFunc();
    void utilGreatFunc();
}

what is the best way of doing this? I suppose the namespace way, it is much clearer to me and simpler to write. Or maybe there is some other and better design?

Answer 1

You never use a “utility class with static methods” in C++. That’s a Java-ism. Instead, use your second solution and put the functions in a namespace.
